Dynamic buckle propagation on Chater's beam
-
摘要: 本文从非线性有限元的一般方法出发,结合应用加权残数技术和ALE边界元法,对Chater梁的屈曲传播进行了完全的动态分析,抛弃了前人一直采用的准静态和动稳态假设;另外,基于势流理论和非线性液面条件,还考虑了结构充液后由于流固耦合作用对屈曲传播所造成的影响,大量算例揭示了结构的菲线性、作用载荷、屈曲传播速度以及液体介质之间的内在关系,从而对屈曲传播有了更深入的认识。Abstract: In this paper, a sweeping investigation on dynamic buckle propagation on Chater's beam is performed by using the general nonlinear finite element methods (FEM)instead of any quasi static or dynamic steady propagation assumptions, With the help of the arbitrary Lagragian -Eulerian boundary element method (ALE-BEM) and the weighted residual methodology,the effect of interaction between the beam and the fluid flow inside is also reconsidered based on the two-demensional potentional flow theory.How the structur...
